Simaudio Moon Evolution 650D DAC and CD Transport


Fantastic modern DAC with a built in CD transport, capable of playing just about any format CD. 

$9,000 Original MSRP -  and this piece also has 1 year and two months (14 total months) remaining on the warranty against manufacturer defects (excluding mechanical defects).

In perfect working and cosmetic condition.  Complete with all accessories and packing materials.  

The Simaudio Moon Evolution is one of my all time favorite lines of equipment and would be in my top five list if I had to choose a system to suit me for the rest of my life. 

This particular piece is a very capable DAC with the bonus of built in CD transport. It can be upgraded to the next level with the addition of an 820S external power supply. Frankly, I dont think it needs it, but if you're a tweaker this might be just for you.

It also has one of the most readable displays in the industry visible from just about any angle and distance. 

The casework in the best I’ve seen with amazing fit and finish. It utilizes the heaviest gauge metal panels and heatsinks I've seen in this category. 

Condition is near perfect, not a visible scratch or fingerprint. All functions work as they should and it has been fully tested. 

Comes complete as it would from the factory including the manual, remote, spikes, and packing materials (double box).

From a great review by Michael Fremer via Stereophile:

"Working through my mostly 16-bit/44.1kHz playlist, I was struck by the 650D's consistent overall sound: unusually transparent, delicately drawn, and ethereal, with an almost complete absence of digital glare and hardness. Yet the 650D accomplished this without noticeably softening instrumental attacks or smothering natural transient sharpness. Reverb trails were easy to follow as they naturally faded to black in an analog-like fashion similar to what I remember hearing through dCS's Debussy USB DAC ($10,999). I wished I'd still had the Debussy on hand for a direct comparison, but no such luck."
